Editing GOST (block cipher) (section)

==GOST 2-128==
	
GOST 2-128 was released in 2016.<ref>{{cite web |url=https://github.com/bobman78/GOST2-128|website=Github |title=GOST2-128 in C language }}</ref> It has exactly the same design but has twice as many S-tables and uses 64-bit integers instead of 32-bit integers. It no longer works on 64-bit blocks but on 128-bit blocks like AES.
	
The two S-tables are those of the Central Bank of Russian Federation and that of the GOST R 34.12-2015 standard.
		
GOST had 256-bit keys that were reused as subkeys. In GOST 2-128, subkeys are generated by a one-way hash function, representing 4096 bits. Thus, no weak keys exist and attacks against GOST do not work in GOST 2-128.
